Evolution of the MBH mass in the MAD (shown as a solid orange line) and HMAD (shown as a dashed blue line) simulations. For comparison, we also show two dot-dashed black lines corresponding to the MBH growth for a constant Eddington accretion. The thick line starts at t = 500 Myr (consistent with the HMAD case), and the thin line starts at t = 350 Myr, immediately after seeding.
